Abstract

a -Hydroxybenzylpenicillin is produced by reacting 6-aminopenicillanic acid with mandelic acid or a salt or derivative thereof at pH not exceeding 9 in the presence of a penicillin amidase enzyme preparation derived from a penicillin amidase-producing bacterium such as Escherichia coli and subsequently recovering the a -hydroxybenzyl-penicillin. Mandelic acid derivatives which may be used include mandelamide, mandelic acid esters and a -hydroxyphenol-acetylthioglycollic acid.
